In biological systems, maintenance of pH is critical as it affects the functionality of macromolecules. Buffers consist of aqueous solutions of weak acids and their conjugate bases, or weak bases and their conjugate acids. Ideal buffers will possess a neutral pKa, high water solubility, and be nontoxic to cells and inert to other components present.
High purity standards of single elements are important for calibration and reference use in analytical and environmental applications that include ICP, DCP, and mass spectrometry.

Buffers for life science research
The purpose of a buffer in a biological system is to maintain intracellular and extracellular pH within the physiological range, and resist changes in pH due to the presence of internal and external influences. Our buffers have pKa values at or near physiological pH, and offer minimal interference with biological processes, making them suitable for cell cultivation, isolation of cells, enzyme assays, and other life science research applications.
